Vardenafil relaxes muscles of the blood vessels and increases blood flow to particular areas of the body. Vardenafil is used to treat erectile dysfunction (impotence).

Vardenafil may also be used for purposes not listed in this medication guide. What is the most important information I should know about Levitra ?

You should not use vardenafil if you are allergic to it, or if you take other medicines to treat pulmonary arterial hypertension, such as riociguat (Adempas).

Vardenafil is not approved for men younger than 18 rite aid sildenafil price years old. Do not take vardenafil if you are also using a nitrate drug for chest pain or heart

problems

Taking vardenafil with a nitrate medicine can cause a sudden and serious decrease in blood pressure.

Tell your doctor if you have ever had: heart disease, heart rhythm problems; a heart attack, stroke, or congestive heart failure; long QT syndrome (in you or a family member); high or low blood pressure; seizures; liver disease, kidney disease (or if you are on dialysis); a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia; a bleeding disorder such as hemophilia; a stomach ulcer; hearing or vision problems, vision loss; an eye disorder such as retinitis pigmentosa (an inherited condition of the eye); a physical deformity of buy liquid sildenafil citrate the penis (such as Peyronie's disease); or if you have been told you should not have sexual intercourse for health reasons. Vardenafil can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people, most of whom also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoked or were over vensun sildenafil 50 years old.

It is not clear whether vardenafil is the actual cause of vision

loss

Vardenafil is not for use in women, and the effects of this medicine during pregnancy or in breastfeeding women are unknown.

Vardenafil (Levitra®) is the second oral phosphodiesterase inhibitor approved for erectile dysfunction. 1, 2 As well as sildenafil (Viagra®), this drug acts by relaxing blood vessels and muscles in the penis, allowing increased blood flow into the penis to produce an erection.

The most important hazard adverse effect related with this therapy is the promotion of a profound hypotension and myocardial ischemia when combined with nitrates.

Cases of atrial fibrillation had been related with sildenafil 3, 4 but, with vardenafil therapy, this arrhythmia was not described yet.

We report a case with a first-detected, symptomatic paroxysmal atrial fibrillation in a healthy patient after a self-medication with vardenafil.

A 50 year old man presented to the emergency room with a persistent palpitation, lasting for 2 hours, began 15 minutes after ingesting, as self-medication, a single 10 mg tablet of vardenafil.

He denied other symptoms or the use of ethanol or other medicines.

He had no significant history for erectile dysfunction, and justified the self-medication to improve his sexual performance. He had already used sildenafil previously without complication.

At physical examination, an irregular and tachycardic heart rhythm was evidenced, around 140 beats/minute, with no other pathological findings.

The electrocardiogram revealed atrial fibrillation with rapid ventricular rate and was without ST segment or T wave abnormalities.

Chest radiograph and routine laboratories including cardiac enzymes were normal. Beyond rest, he was medicated with oral diazepam, and the arrhythmia coursed with conversion to normal sinus rhythm after four hours.

He obtained hospital discharge without antiarrhythmic medication.

It was performed on outpatient cardiovascular investigation. The transthoracic Doppler echocardiography disclosed a structurally normal heart, with left atrial diameter of 2.8 cm and left ventricular ejection fraction of 0.76. The 24 hour ambulatory electrocardiographic monitoring did not present cardiac arrhythmias, and the treadmill exercise testing was negative for myocardial ischemia. After a follow-up of 7 months, the patient was asymptomatic, without medication. The temporal relationship between the ingestion of vardenafil and new onset atrial fibrillation in a patient with no cardiovascular diseases suggests that the drug caused the

arrhythmia

Cremers and colleagues 5 demonstrated that sildenafil has a potent vasodilatory action but has no direct influence on human myocardial contractility or proarrhythmic effects in vitro .

Thus, a possible mechanism involved with the induction of atrial fibrillation is hypotension leading to a reflex tachycardia through catecholamine excess. Han and Hoffman 3 reported a case with atrial fibrillation in a patient with normal heart after taking sildenafil. In this case, the patient presented after a syncopal episode, and antiarrhythmic therapy with ibutilide failed to restore normal heart rhythm, which was spontaneously obtained 2 days later.
